  • Patent number: 7445874
    Abstract: A embodiment method for forming a layout for a phase shift mask. A embodiment comprises providing a layout comprising a first feature, a first shifter region and a second shifter region. The first feature preferably has a L-shape portion with an elbow region. The first shifter region is on the outside of the L-shaped portion and the second shifter region is on the inside of the L-shaped portion. The elbow region has an outside corner away from the second shifter region. We identify a phase conflict region caused by the L-shaped portion of the first feature, the first shifter region and the second shifter region. We resolve the phase conflict by modifying the elbow region by moving the outside corner of the elbow region away from the first shifter region and the phase conflict region. The modification of the elbow region further comprises forming a jog region in the line end section of the first feature.

  • Patent number: 7442619
    Abstract: A method of manufacturing a semiconductor device having a substantially L-shaped silicide element forming a contact is disclosed. The substantially L-shaped silicide element, inter alia, reduces contact resistance and may allow increased density of CMOS circuits. In one embodiment, the substantially L-shaped silicide element includes a base member and an extended member, wherein the base member extends at least partially into a shallow trench isolation (STI) region such that a substantially horizontal surface of the base member directly contacts a substantially horizontal surface of the STI region; and a contact contacting the substantially L-shaped silicide element. The contact may include a notch region for mating with the base member and a portion of the extended member, which increases the silicide-to-contact area and reduces contact resistance.

  • Patent number: 7442618
    Abstract: Structures and methods for forming keyhole shaped regions for isolation and/or stressing the substrate are shown. In a first embodiment, we form an inverted keyhole shaped trench in the substrate in the first opening preferably using a two step etch. Next, we fill the inverted keyhole trench with a material that insulates and/or creates stress on the sidewalls of the inverted keyhole trench. In a second embodiment, we form a keyhole stressor region adjacent to the gate and isolation structures. The keyhole stressor region creates stress near the channel region of the FET to improve FET performance. The stressor region can be filled with an insulator or a semiconductor material.

  • Patent number: 7442637
    Abstract: A method for processing IC designs for different metal BEOL processes is provided for enabling fabricating using a metal fabrication process an IC originally having a backend design for a different metal fabrication process. The method first determines layer constructions of an original design of an IC for a first metal backend process, and, based on the layer constructions of the original design of the IC, constructs primitive layer constructions of a target design of the IC for a second metal backend process. The method then tunes an effective dielectric constant of a dielectric layer of the target design to match an associated capacitance of the target backend design with a corresponding capacitance of the original backend design. The method can be used to convert a backend design of an IC from an old metal process (such as Al process) to a new metal process (such as Cu process), without redesigning the IC for the new metal BEOL fabrication process.

    Abstract: A chip is provided which includes a back-end-of-line (“BEOL”) interconnect structure. The BEOL interconnect structure includes a plurality of interlevel dielectric (“ILD”) layers which include a dielectric material curable by ultraviolet (“UV”) radiation. A plurality of metal interconnect wiring layers are embedded in the plurality of ILD layers. Dielectric barrier layers cover the plurality of metal interconnect wiring layers, the dielectric barrier layers being adapted to reduce diffusion of materials between the metal interconnect wiring layers and the ILD layers. One of more of the dielectric barrier layers is adapted to retain compressive stress while withstanding UV radiation sufficient to cure the dielectric material of the ILD layers, making the BEOL structure better capable of avoiding deformation due to thermal and/or mechanical stress.
